What's your motoring etiquette like? Here are the real rules of the road

I am not an angry person, on the whole. I smile at small children, I pat dogs. But then I get into my car and start driving down my street in west London. Oh look, there’s someone driving towards me. I’ll just pull in here to let them past.

That’s the decent thing to do, isn’t it? I’ll just wait for a few seconds to allow them through and they’ll definitely wave at me to say thank you. Or flash their lights (technically against the Highway Code but I’ll allow it). Or nod their head to indicate a tiny crumb of gratefulness.

Then – and this is the crucial bit – they whizz past my car without any of that. Without a cheery little wave. Without any indication of thanks at all. And this makes me properly angry. Explosively angry. An angry bird. So angry I worry that I’m about to go into cardiac arrest in the car. Even angrier than John Cleese in Fawlty Towers when he thrashes his car with that...
